A l k izing this half-speed shaft a plain single caln may be employed.ltwill be noted that the rod which opens the valve, which latter may bethe inlet-valve of the engine, is nioviiig in the proper direction topermit said valve to close when it breaks the sparking circuit, and thespecial recess in the cam assures that this circuit shall not be brokenuntil after the said 'alve shall have closed Having thus described nrvinvention, What 1 claim, and desire to secure by Letters Patent, is-

1. An internal-eoinbustion engine, having a valve to be opened, a rod,slidable in guides, for opening the said valve, the guides for the rod,a can! for operating said rod to open the valve, said cam having in itsoperative edge a special recess, av spring whiehholds said rod inoperative relation with the cam, a laterally )rojecting part on the saidslidable rod, :1. tixed electric contact, a movable elect ic con tact, aspring which holds said conta t: normall in touch with each other, amovable contact-actuating arn'i in the path of said lateral projectionon the rod and adapted to be actuated thereby When the spring on the rodmoves the end of the latter into the recess in the cam to produce aspark between the ,contacts when said I1".0V&bl8 arm is actuated.

2. An internal-combustion engine, having a valve to be opened, a rod Afor opening said valve, a cam B for operating said rod to.

open the valve, said cain having a recess 5, a s )ring 0 which holdssaid rod pressed up to the earn, a projecting part (1 on said rod, arocking spindlef, in the Wall of the combustion-chamber, an arm e onsaid spindle in the path of the part (1, a fixed contact is, acontact-arm g on the spindle f, and a spring h which keeps the contactsnormally in touch substantially as and for the purpose set forth. InWitness whereof I have hereunto signed my name, this 24th, day ofFebruary, 1904, in the presence of two subscribing Witnesses.
